Hey guys, today in this post we are going to learn about How to retrieve opportunity records in custom table invoke apex method using @wire decorators in Lightning Web Component – lwc

The Lightning Web Components programming model has three decorators that add functionality to a property or function.

@api:- To expose a public property, decorate a field with @api. Public properties define the API for a component.

To expose a public method, decorate it with @api. Public methods are part of a component’s API. To communicate down the containment hierarchy, owner and parent components can call JavaScript methods on child components.

@track:- If a field’s value changes, and the field is used in a template or in a getter of a property that’s used in a template, the component rerenders and displays the new value. If a field is assigned an object or an array, the framework observes some changes to the internals of the object or array, such as when you assign a new value.

@wire:- To read Salesforce data, Lightning web components use a reactive wire service. When the wire service provisions data, the component rerenders. Components use @wire in their JavaScript class to specify a wire adapter or an Apex method. To know more details about Decorators, Click Here..
